A tympanic membrane, (is also called a tympanum), is the circular patch of skin directly behind the frog’s eye that we commonly call an eardrum. It functions much like our’s does.
The tympanum sends sound waves to the middle of the war then to inner ear, which allows a frog to hear both in the air and below water.

Chantek the orangutan is one of many nonhuman primates that scholars have used to draw conclusions about the origins of human language because they seem to be able to communicate through sign language.

Golden eagles have adapted their behavior for living in temperate
grasslands by building their nests on the ground.
Temperate grassland is characterized by mainly grasses and very few
trees. Animals like the Golden eagle who build their nests on tall trees are
able to adapt to the absence of these types of trees in the grasslands by
building their nests in the ground.
They live in in pairs in the temperate grasslands to efficiently guard the
nest and hunt animals for their survival.
